Display Module - 7" Touchscreen LCD

Description: This display module from 4D systems is the uLCD-70DT, a 7.0” intelligent touchscreen LCD powered by the DIABLO16 graphics processor. The uLCD-70DT is designed for applications demanding a large intelligent display module, and is the largest size available from 4D Systems.

The DIABLO16 Processor offers considerable FLASH and RAM upgrades over the PICASO processor, and also provides mappable functions such as I2C, SPI, Serial, PWM, Pulse Out, and Quadrature Input, to various GPIO, and also provide up to 4 Analog Input channels. The uLCD-70DT also features 2mm pitch male headers to connect an optional module. 4D Systems intends to bring out one or more modules which will be compatible with the uLCD-70DT, offering connectivity such as WiFi or Bluetooth. This will enable the uLCD-70DT to connect with remote devices.

Customer Comments

Using the Workshop 4 software to compile and upload through the serial-to-USB converter, you can write a message and draw shapes on the 7" touchscreen. If you are using a different 4D touchscreen, make sure to change your platform. I was using the ViSi environment.

Why doesn’t this one have the micro SD card slot populated. It seems the smaller screens have it populated. It would seem a larger screen could use more graphics and have a greater need for extra storage. Does this screen have differences other than screen size compared to the 4.3" touchscreen LCD here: https://www.sparkfun.com/products/11740?

Sorry, I missed that it was the full size SD that wasn’t populated and that the Processor is more capable. I still want to confirm that this unit is as capable, if not more, than the smaller screen sizes. Thanks!

This is the next frontier for manufacturers. I mean, the RPi has more computing power than the entire Apollo program (ground stations and spacecraft) for a nominal $35, but to interact with it with a measly 7" screen costs 5 times as much. For that matter, for essentially the same price you can buy a 17" touch screen monitor. It’d sure be nice if the price would scale with the size. I know that there’s all sorts of reasons for this having to do with market size, amortizing tooling, engineering overhead, etc., but it still feels wildly disproportionate, even if it isn’t really. It’d be nice to have a screen that’s about the same size as the RPi for about the same price as the RPi.

It should with the proper connections. All the Beaglebone Black/RPI/arduino is doing is feeding it information. Just follow the instructions and hook +5V, GND, RST, RX, and TX to the appropriate ports on your BBB and you should be on your way to one epic project!

Great display

Although it is pricey, this display gets the job done. I have used it’s smaller 3.2 and 4.3 inch brothers on other projects. I am making this one with a connector on a cable so it can be used on multiple projects.

I am dissapointed that you are not carrying the matching bezel for this screen, which is confusing because you carry them for the other sized screens.

Excellent Quality

The only little annoying thing is the fact that you have to connect and disconnect your uSD from your computer in order to load the program in the touchscreen. Other thing, is that you have to pay extra for the license of the software with convenient features for the programmer, I think that if you spend $180 in a touchscreen at least they have to give a one computer license

Great Product

This module is the greatest. It’s easy to connect and program. 4D systems knows how to make a high quality product and provides the necessary software tools to support it.
On a scale from 1 to 10, I give it a 12:)

Pretty cool

I was able to get a project up and running very quickly at work with this screen. Easy to use and program with their software package. Graphics are nice. I like using it so much I bought a 4.3" for myself. I wish it could be a kitted with the bezel, stand, Arduino adapter, and any cables needed.

Fault Disply

Last year I bought more than 15 Display Module - 7" Touch screen LCD and .. 2 moth back I got 3 LCD ine of them have fault its not working alsy 8 month back I got some LCD one of that also same Issue there is 2 Screen Now have fault what shall I do ??
